Expansion
POSTERIOR EXPANSION Reshaping the arches. Tapered, Omega or Square forms need to be reshaped into ovoid form. Expansion. Expand narrow arches. Average transverse measurement = 33-37mm. Clincheck instruction for cases that require expansion: “This case requires expansion. Please expand across the U6 teeth ___ mm each side…
Canine distalisation (to open space for a lateral incisor)
 If the canine requires distalization, mesiodistal root tipping, and torque control, then a good suggestion is: The control of all those movements can be achieved with the use of rectangular and vertical attachments. Implant placement With today’s implant technology, assuming a 3.25-mm lateral incisor implant…
Class II div 2
In Class II division 2, the upper incisor’s torque is essential for the correction. The more retroclined the upper incisors are, the more posterior anchorage will be needed. This is the reason why, in some severe Class II division 2, a posterior microscrew is need…
Anterior open bite
Open Bite Prescription POSTERIOR TEETH INTRUSION Place 4 mm wide occlusally beveled rectangular attachments on the uppers 4’s and 5’s to support the intrusion of the molars. Here’s one more tip—overtreat the intrusion of the molars to a 2 mm posterior open bite, as aligners…
Deep bite
This type of malocclusion can cause: There are 4 possible components for deep bite correction. Not all these components apply toevery case. Deep bite attachments Add Horizontal-Incisal-Beveled attachments to available posterior teeth in extremely deepbite cases. Goal = 1 per quadrant. This will boost anchorage….
Pontics
It is imperative that esthetics be maintained in extraction cases (or in case of missing teeth). Pontics are placed by default on anterior spaces greater than 4mm. Full or half size pontics? Pontic Filling Pontics can be filled: Ectopic Canines Extract virtually and ask for…
